ROD GONG FOR STRIKIN G CLOCKS.

Application filed April 13,

T0 aZZ whom it may concern Be it known that I, lVILsoN E. PORTER, a citizen of the United States, residing at New Haven, in the county of New Haven and State of Connecticut, have inventeda new and useful Improvement in Rod Gongs for Striking Clocks; and I do hereby declare the following, when taken in connection with the accompanying drawings and the characters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this application, and represent, in

Fig. 1 a detached perspective view of a set of rod-gongs embodying my invention, and mounted as for use in a chime-clock.

Fig. 2 a broken view, partly in elevation and partly in section, showing the outer end of a rod-gong as provided with one of my interchangeable tuning-buttons.

Figs. 3, t, 5 and 6 det ched views 111 side elevation of a series of such buttons.

Fig. 7 a broken sectional view of the outer end of one of the rod-gouge, with the weight thereof removed.

My invention relates to an improvement in rod-gongs for chime-clocks, the object being to provide simple means whereby they may be conveniently and accurately harmonized and tuned, without recourse to changing their length for the purpose.

\Vith these ends in view, my invention consists in a rod-gong having its outer end counterbored and threaded, in combination with a series of interchangeable, tuningbuttons differentiated in weight, each having a threaded stem for insertion into the bore of'the rod, the pitch of which will respond to the weight of the button chosen.

My invention further consists in a tuningbutton of certain construction and form as will be hereinafter described and pointed out in the claims.

In carrying out my invention, as herein shown, each of the rod-gongs 10, 11, 12 and 13 is formed in its outer end with a threaded counterbore 1.4 for the reception of the threaded stem 15 of any one of a plurality of interchangeable, nut-like tuning-buttons 16, 17, 18 and 19 differentiated in weight,

Specification of Letters Patent.

1922. Serial No. 552,310.

While I have shown only four differentiated weights, of course that number may be great ly increased, if more refinement of tone is called for. The inner ends of the gong-rods are mounted in a cast-metal mounting-base 20, provided with an integral, offsetting mounting-flange 21 having screw-holes 22, by which the set of gongs is secured in the clock. The said flange 21 offsets from the base 20, so that the inner face thereof does not make contact with the surface to which the flange is applied. The rod-gong 23 is furnished for use in strikin the hour and having no part in the chiming function of the clock, is notadapted to be provided with one of thebuttons. As shown the buttons are made with facets, giving them a nut-like form, whereby they are adapted to be applied and removed with any ordinary wrench, but I do not limit myself tomaking them of any particular form.

I claim:

1. A rod-gong for striking-clocks, having its outer end counterbored and threaded, in combination with a plurality of interchangable tuning-buttons differentiated in weight, each button having a threaded stem adapted to be entered into the said bore.

2. A. rod-gong for striking-clocks, having its outer end Counterbored and threaded, in combinationwith a plurality of nut-like, interchangeable tuning-buttons differentiated in weight, each button having a thread ed stem adapted to be entered into the same bore.

In testimony whereof, I have signed this specification in the presence of two subscrib-
